Title: Semiconductor device
Inventor: HIRASHIMA TOSHINORI
IPC: H01L23/50
Filed: 1984-12-19
Abstract: PURPOSE:To protect lead outer ends from bending by a method wherein a portion of a resin-sealed main body is extended and a framework is provided to encircle the outer ends of a plurality of leads. CONSTITUTION:Leads 3 are combined by dams 8 for the prevention of the leakage of resin. Portions 9 of the dams 8 are caused to extend outward from the four corners of the sealed main body. The outer ends of the leads are combined to outer dams 10. A neighboring unit is connected to the outer dams 10 of a framework 11. A chip 1 is attached to a tab 2 and wiring is made between them. When placed between a top force 12 and bottom force 13, the dams 8 and 10 are outside the cavity 14 of the metal moulds, which prevents the sealing resin from leakage. When the resin is hardened, the dams 8 and 10 are separated from the leads 3 at points 15, separating the leads 3. A unit is thereby separated from neighboring units for the completion of the semiconductor device.

Title: Solid state laser oscillator
Inventor: YUASA HIROSHI
IPC: H01S3/094
Filed: 1990-10-05
Abstract: PURPOSE:To prevent input of a feedback signal to driving means of a laser diode by providing a limit controller which outputs a drive signal for driving the driving means when the feedback signal from a feedback controller is a predetermined value or more. CONSTITUTION:A feedback signal of a voltage responsive to the intensity of a laser light L to be detected by a photodetector 8 from a feedback controller 21 is outputted to a limit controller 22. If the feedback signal is larger than a set voltage applied previously to a fourth differential amplifier 32, a drive signal responsive to the difference is output to a driver 7. Thus, since the driver 7 drives a laser diode 6, the output of the light L is maintained constantly. That is, if the feedback signal is higher than the vicinity of a threshold value, a drive threshold value is outputted from a limit setter 22 to the driver 7, and hence the diode 6 is controlled to be driven so that the output of the light L becomes constant by the drive signal.

Filed: 1987-10-21
Abstract: PURPOSE:To eliminate the need for a mechanical movable part, to improve the reliability, and to make the title element compact by controlling the area of the hole part in the center of an annular elastic body by utilizing repulsion force based upon the Meissner effect between a magnetic field and a superconductor. CONSTITUTION:A coil 5 is arranged in front of the elastic body 2 which contains the superconductor 3 and then the magnetic field which is larger in magnetic flux density at the center part of the annular elastic body 2 than at its peripheral part is established. Thus the magnetic field 6 is produced by the coil 5, and consequently the superconductor 3 receives force in its outer peripheral direction by the Meissner effect of the superconductor 3, so that the superconductor 3 becomes stable at the position where the shrinkage force of the annular elastic body 2 is balanced. The internal area of the annular elastic body 2, therefore, increases and the quantity of luminous flux passing through it increase. Consequently, no mechanical driving part is necessary, the reliability of the device is improved, and the device is made compact.

Abstract: PROBLEM TO BE SOLVED: To provide a constant quenching ratio despite of the variance of the insertion loss of an electric field absorption-type optical modulator (EA modulator) by connecting a photo current absorption quantity control circuit controlling photo current absorption quantity to a DC photo current absorption circuit. SOLUTION: The photo current absorption quantity control circuit 8 operates monitor PD(photo diode) current quantity generated by lightreceiving LD(laser diode) back light 15 as a reference. The circuit controls photo current absorption quantity proportional to the output of an APC(automatic power control) circuit 7. The circuit is connected to a DC 2 photo current absorption circuit 4 and therefore the DC photo current absorption circuit 4 can execute an absorption operation proportional to APC circuit output. Since APC circuit output is proportional to the intensity of LD output light 13, the photo current absorption quantity control circuit 8 can be connected to the DC photo current absorption circuit 4. Thus, the DC photo current absorption circuit 4 can execute the photo current absorption operation proportional to the intensity of LD light output 13.
